Officials put the new facility near the city of Qom, and the IAEA indicated that while it is still about a year from operation and has no nuclear material in it yet it will have less than half the capacity of Iran’s existing facility at Nanatz. The centrifuges at the new site will be domestically designed and potentially more efficient than the aging imports used in Nanatz.

". . . it is not clear Iran has broken any rules with the new construction."

To anyone not contriving to gin up a case for sanctions and war, there's nothing ambiguous at all about what the Iranians have done. They built a nuclear facility, as they are permitted to do under the NPT regime, and then declared it to the IAEA before it became operational. It's all very much by the book. The confusion is deliberately created by Zionist and FedGov agitprop.
